It turns out that the error check for duplicate PKs is only invoked if you tell this code that it's being invoked by ALTER TABLE, and my original patch wasn't. I changed it and now everything seems to behave as expected. I added a test case pretty much like yours, which now works correctly. I also added another one where the bogus PK is two levels down rather than one. This is because I had originally developed a different fix -- which fixed the problem for your test case, until I realized that since this code is recursive, we could cause trouble at a distance.
